Detailed Explanations
2010 ActiveHybrid 7 (E65/E66)
The 2010 ActiveHybrid 7 marked BMW's entry into the hybrid luxury sedan market. It utilized a mild-hybrid system featuring a V8 engine and an electric motor. While innovative for its time, its primary focus was on boosting power rather than achieving significant fuel economy gains. The electric motor provided a power boost during acceleration, improving overall performance. However, due to its early hybrid technology, it suffered from limited electric-only range and potential reliability issues with the hybrid components. Prospective buyers should be aware of the potential for expensive repairs related to the hybrid system.
2013-2015 ActiveHybrid 7 (F04)
The 2013-2015 ActiveHybrid 7 represented a significant improvement over the 2010 model. It featured a more sophisticated hybrid system with a larger battery and a more powerful electric motor. This resulted in better fuel economy, increased electric-only driving capability, and a smoother integration of the electric motor and engine. The interior was also refined, offering a more luxurious experience. However, the hybrid system remained complex, and potential buyers should be prepared for higher maintenance costs compared to non-hybrid models. The 2013 model year, being the first year of this generation, might have some initial production kinks that were ironed out in later years.
2016-2019 740e iPerformance (G11/G12)
The 2016-2019 740e iPerformance (later renamed 745e) represented a major leap forward. This model was a plug-in hybrid, offering significantly increased electric-only range. It featured a more powerful electric motor, a more efficient engine, and improved overall performance. The plug-in capability allowed drivers to charge the battery from an external power source, further reducing fuel consumption and emissions. The G11/G12 generation also benefited from advanced technology features. However, the increased complexity of the plug-in hybrid system meant potentially higher repair bills, especially related to the high-voltage components. While these models offer the best combination of performance and efficiency, they also require specialized maintenance and might experience depreciation as hybrid technology continues to evolve.
